一道高中英语单项选择
Pigs ______ in our school _________ the food we students have thrown away．
A.fed；feed on \x05B.are fed：live on
C.that are fed；feed with \x05D.fed：feed to
求理由,然后为什么不选C
答
feed on sth ：以.为食物,是固定词组.
be fed with sth：被喂养.食物.
第一个的fed,非谓语动词,等语that are fed
但是第二格的谓语动词只能用feed on 或者are fed with
希望能帮到您.
